DESCRIPTION
The VS-50WQ03FNPbF surface mount Schottky rectifier
has been designed for applications requiring low forward
drop and small foot prints on PC board. Typical applications
are in disk drives, switching power supplies, converters,
freewheeling diodes, battery charging, and reverse battery
protection.
